At 2.0 mm OD, natural PTFE offers 1.0 or 1.2 mm ID, giving different wall thicknesses. Select by length, flow and allowable pressure drop; check the size table and end connection.
PTFE Flanged Tubing Assembly
FOREACH PTFE flanged tubing assemblies use natural PTFE tubing, matching fittings and washers to connect flat-bottom instrument ports. They can be configured for reagent and cleaning-fluid lines in in-vitro diagnostic (IVD) and automated analytical equipment. Available tubing IDs span 0.5–2.0 mm, with ODs of 1.6, 2.0, 2.5, 3.0 and 3.2 mm. Select the listed ID/OD pairs and specify single- or double-flanged ends and finished length in the drawing.
PPS, PVDF and PEEK fittings are available in standard and compact structures, with M6×1 or 1/4-28 UNF threads and support washers matched to the connection model. Define A/B fitting materials, threads and connections separately; coils, protective sleeves, stop tubes and labels are optional. Confirm material compatibility against the working fluid, cleaning fluid, concentration and contact time. Samples and batch assembly are supported. Confirm working pressure and temperature for the specific dimensions, ports and complete assembly.
FOREACH holds ISO 9001 and ISO 13485 quality management system certifications.
Typical Applications:
Reagent transfer line connections, Cleaning-fluid line connections, Flat-bottom port connections, Instrument fluid-path integration

These are available tubing sizes. Confirm flange dimensions and mating ports against the assembly drawing.
Match fitting material, structure and thread to the corresponding model.
Miniature option: 6-40 UNF, PEEK fitting, 1.6 mm tube OD. Confirm the complete end configuration against the selected model.
Working pressure and temperature must be confirmed for the specific assembly configuration.
Matching fittings and 2D drawings
The table lists fitting series, threads and body materials for 1.6 mm tube OD as examples. Select the drawing by material and full model number; confirm matching parts for other ODs during customization.
